Hi Boki_Srb and Wojpen,

thanks for replies. In any case, I have following entries in sys.txt

[folders]
linked_root_list="/storage/9016-4EF8 /Card/Android/data/com.nng.igoprimoisr2013march24.javaclient/files/iGO"
has_secondary_root=0
;android_secondary_root_path="/storage/extSdCard/addons"

and put all content files to SD Card (I did not copy anything to tablet's internal memory)

.fbl + .fda + .fpa -> Galaxy Tab S2\Card\Android\data\com.nng.igoprimoisr2013march24.javaclient\files\iGO\content\map
.3dc + .3dl -> Galaxy Tab S2\Card\Android\data\com.nng.igoprimoisr2013march24.javaclient\files\iGO\content\building
.poi -> Galaxy Tab S2\Card\Android\data\com.nng.igoprimoisr2013march24.javaclient\files\iGO\content\poi

and everything is working fine. I just checked it and have POIs available as well as 3d buildings are displayed
on map.

So, from my point of view, it is functional and I will not change anything in sys or storage :-)

Maybe the view during navigation should be lower (closer), but I do not want to bother you and will try
to find any solution/advice on the web.

Thanks so much !!!
